C#编写ISAPI筛选器

[phisy]

请问有没有谁写过ISAPI筛选器?

我想实现限制来源网站,,

比如只有从www.xxx.com过来的才能访问我这个网站.

获取客户端IP:

private string GetClientIP()
{
string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}

if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.UserHostAddress;
}
return result;
}
